Thourio (Greek: Θούριο, Bulgarian: Каблешково - Kableshkovo, Turkish: Urlu) is a village in the northeastern part of the Evros regional unit in Greece. Thourio is in the municipality of Orestiada. It is located between Orestiada to the north and Didymoteicho to the south, about 4 km west of the river Evros, that forms the border with Turkey here. The nearest villages are Neo Cheimonio to the north and Sofiko to the south. Thourio is on the Greek National Road 51 (Feres - Soufli - Didymoteicho - Orestiada - Ormenio - Svilengrad), and has a station on the Ormenio - Didymoteicho railway.
Urlu, as Turks named the present Thourio, was ruled by the Ottoman Empire until the First Balkan War in 1912. It was an important railway station on the line Adrianopol-Thessaloniki. Urlu joined Bulgaria during the First Balkan War and according to the Treaty of London (1913). The Treaty of İstanbul (1913) returned it to Turkey, but in 1915, during World War I, Turkey ceded the area of Didymoteicho to its ally Bulgaria, and the town was renamed Kableshkovo. During the Greco-Turkish War (1919-1922) it was ceded to Greece and it received the present name. Its Bulgarian and Turkish population was exchanged with Greek refugees, mainly from today's Turkey.
